GIS Big Data

SuperMap iManager supports to ‘one-click’ creating GIS Big Data environment. As the GIS Big Data solution, the environment includes HBase, Spark, and HDFS, it supports a high effect storage, search, extend, process, and analysis for super large scaled spatial data.

For monitoring and managing, users can understand the associations between the services; redeploy the services; adjust the specs of service; modify the images of service; expose/hide the services address;view the log of the services; control the command pad of containers; and manual/automatic scaling the services.

The main services in the GIS Cloud Suite environment are listed below:

• DataNode: HDFS(distributed files system), to achieve unstructured data storage.
• FTP: The protocol of files transfer, used for transferring data between local storage and iServer.
• HBase-hue: The client of HBase database.
• HBase-master: The master node of HBase database.
• HBase-Regionserver: The regionserver node of HBase database.
• iServer: The cloud GIS application server SuperMap iServer, has the abilities of publishing 2D/3D services, managing, aggregation, and extention services.
• MySQL-Server: MySQL database, used for storing account information of iServer.
• Namenode: HDFS(distributed files system), files directory tree.
• PhpMyAdmin: The management tool of MySQL database, manage MySQL by Web client.
• Spark-Master: The master node of Spark computing engine.
• Spark-Worker: The worker node of Spark computing engine.
• Zookeeper: The distributed application coordinate service, it is an important component of HBase, used for coordinating HBase.
